GASHBURNER FOR BILLIARD-TABLES.

SPECIFICATION forming part of Letters Patent No. 397,904, dated February 19, 1889.

Application filed l'uly 2'7, 1888. Serial No. 281,209. (No model.)

To all whom t may concern,.-

Be it known that I, WILLIAM F. FOLMER, of New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Gas-Burners :for Billiard- Tables, of which the followingis a specification. l

I will describe a gasburner embodying my improvement in detail, and then point out the novel features in claims.

In the accompanying drawings, Figure l is a side elevation of a gas-burner embodying my improvement. l Fig. 2 is a rear elevation of the same. Fig. is a vertical section of a portion of the burner, taken on the plane of the line a a', Fig. l. Fig'. e is a transverse section of the same, taken on the plane of the line y y, Fig. 3. y

A designates a gas-supply pipe, which may extend from any suitable fixture.

B designates the shell of a gas-cock, secured to the supply-'pipe A by means of a nipple or coupling-piece, a', on the shell of the cock.

O designates the plug of the cock. The plug of the cock for that portion thereof which extends into the shell is inade tapering and lits a correspondingly-tapered cavity in the shell. The plugl is provided with a longitudinally-extending gas-passage, a', and another gas-passage, c?, opening at one end into the gas-passage a', but extending at approximate right angles to the latter. The passage c? also opens into a central cavity, o?, formed in a nipple or nozzle, C, madeas here shown, integral with the main body of the plug of the cock and extending' at approximate right angles thereto beyond the shell B.

Communication between the su pply-pipe A and the gas-passage a of the plug is afforded bymeansot' a short gas-passage, a", extending at approximate right angles to the passage a and occupying such position inthe plug' that when the latter is rotated sulticiently far the passage from the su pply-pipe and the passage a will intercmumunicate. lt isnot intended in practice, however, that the communication between the supplypipe A and the passage CL4 shall ever be wholly closed. To accomplish this I provide the plug' of the cock with a circmnferential groove, a5. (Shown in Figs. 3

and l.) This groove affords communication between the gas-supply pipe and the passage ai. I prefer to make the groove tapering. In other words, it will be deepest where it joins the passage a4, and will gradually vanish upon the surface of the plug. The object of this will bemore fully explained hereinafter.

One end of the shell B of the cock is shown as recessed. XVithin this recess is arranged a coil-spring, l). This coil-spring surrounds an outwardly-extending portion, 1)', of the plu g of t-he cock. It abuts at one end against the shell of the cock and at the other against a washeigbz. Outward movement of the washer 'b2 is prevented by means of a cross-bar, D,

rigidly secured to the portion D of the plug of the cock. The spring i) operates to hold the plug' of the cock firmly in its seat. The outer end of the portion b of the plugI is grooved to receive the cross-bar D, and the latter is secured at. about midway in its length within said groove, as here shown, by means of a screw, c. The cross-bar I) is employed to rotate the plug of the cock. I have shown chains d secured to the cross-bar near the ends of the latter. Bypulling upon one or the other of these chains, as required, the plug of the cock may be rotated in any desired direction.

lThe cavity a3 in the nozzle or nipple O of the plug' is internally screw-threaded to receive a pipe, d?. In the other end of the pipe d2 is secured a burner-tip, (Z3. The pipe d2 and. the tip d3 constitute the burner proper.

E designates a globe, of glass or similar material. This globe rests at its lower edge in a metallic globe-holder, e, which latter is provided centrallywith an opening through which extends the pipe d2. The globe-holder is also perforated to form an air-distributer. Its outer edge is turned upwardly to form a Iiange, e, extending about the lower edge of the globe. Lips or lugse"2 on the Bange e may be bent over the lower edge of the globe to retain the lat-ter in position. The globeholder e has a pivotal connection with one end ot' a link, F. The latter near its other end is in the example of my improvement shown provided with a longitudinal slot, f. Into this slot extends a pin, f ,y which latter extends from an arm, G, rigidly mounted on IOO the shell B of the cock. -lVhen the plug of i the cock is rotatedby means of the cross-bar l D in such manner as to throw the pipe (P into the position shown in dotted outline in liig. l, not only is the gas turned on,but1,be globe E is moved backwardlyalongthe pipe d? and away from over the tip di), so thai` a I ull flame ot' gas may issue from the tip. lhe rotation of thc plug ot' the eoclc in the other direction, or in the direction to turn the gas olii', throws i lthe arm rl? into the posi tion shown in full li ncs in Figs. l and and causes the globe E to be moved along the pipe di and into a position to surround the tip of the burner. lhen being moved into the latter position, the is cut off gradually, owing to the tapering groove di in the plug, until when in the extreme positions illustrated in full lines in Figs. 'I and 2 a mere thread of flame may, it desired, be left at the limrner-ti p, which, owing to the protcction ol the globe IC, will not bc extinguished by gusts oi air.

llyproviding the link l? with a ltmgitudinal slot at i ts point oi.' conn cction with the arm l the plug oli' the cock may be rotated li'or a conp siderable distance without el'iceting any movement of the globe E, because the link l will y slidealong on the pin j". lly this means danger ol" breaking the globe is avoided, as the tlame will not be ol' sul'lieient dimensions at any time while the tip is within the globe to come in contact with it and cause fracture.

.It will be seen that the shell ol. tbe eoclc is provided with a projectiim, y, and that the cross-bar l) is provided with ai'ljustable stops g', adapted to contact with the proiection y as the cross-bar is moved in either dircctioil. These ad j ust-able stops in this example ot' my improvement consist ot' screws working in tapped holes in the cross-bari). .lymanipulating these stops a less or greater range of movement maybe given to the cross-bar, and eonscfjluentlyto the plngolf thecock,\vhereby a greaier or lesssupply oli' gas may be allowed to pass to the lmrner-tip, as desired.

I have shown a smoke bell or reiiector, H, supported from an arm, 71, secured to the pipe g A. This smoke-bell will preferablybe of such i size as to always be in proper position above the burner. .Y

ly my improvement l provide a means for always nmintaining a light at the burner-tip and Ior readily bringing the burner into a proper position above a billiard-table, While by this movement the gas is turned on. in the desired force. l also provide m cans lfmreadil y varyin the llow of 'What l claim as my invention, and desire lo secure by Letters Patent,`is-

l.. The combinati on,with a gas-su pply pipe, ot a gas-cock having' a rotary plug, and a gasburner secured to said plug and moving therewith to occupy substantially vertical and horizontal positions, and a globe connected to said gas-cock and sliding on the burner as it is moved from one position to the other, substantially as specified.

2. The comliiination,with a gas-supply pipe, ol' a gas-cock having a rotary plug, a gas-burner secured to said plug and having a movement therewith to occi'ipy approxi mately vertical and horizontal positions, a globe for the burner, a rigid supliort, and a swinging con ncction between the globe and said support,

whereby when the burner occupies avertie-al position the globe will surround the burnertip, and when the burner occupies a horizontal 'position the globe will be moved `from over th e burn er-ti p, substantially as specified.

il. The combina-tion,with a gas-supply pipe, of a gas-cock having a rotary plug, a gas-burner secured to said plug and movin(r therewith io occupy approximately vertical and horizontal positions, a globe for the burner surroundin g the burner-tip when in one position and removed from said tip when in its l other position, a rigid support, and a link having a pivotal connection with said globe near one end and having a slotted connection with said support nearthe other en d, substantially as sijiecilied.
